what does it mean translate the figure 5 units up
Answers
By definition. a Translation is a transformation in which a figure is moved a fixed distance in a fixed direction.
The Image is the figure obtained after the transformation and the Pre-Image is the original figure.
In this case, you know that the figure shown in the picture must be translated 5 units up. Therefore, the rule for this transformation is:
[tex](x,y)\rightarrow(x,y+5)[/tex]You can identify that the marked point on the Pre-Image has the following coordinates:
[tex]\mleft(-4,-3\mright)[/tex]Therefore, applying the rule for this transformation, you get that the coordinates of the marked point in the final figure, are:
[tex]\mleft(-4,-3\mright)\rightarrow\mleft(-4,-3+5\mright)\rightarrow(-4,2)[/tex]The answer is:

Answers
The value of y-coordinate from the given information is 36.
Given that, the water level rises 12 centimeters every 7 minutes and you record the data point of (21, y).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
According to the question the water rises 12 cm every 7 minutes. Taking x to represent the time in minutes and y to represent the rise in cm then, find the rise y in time x as;
7 minutes = 12 cm
1 minute
(1×12)/7 = 12/7
Hence in 1 minute, the rise is 12/7 cm
Thus in 11 minutes, the rise will be ;
21 × 12/7 = 3 × 12 = 36 cm
So, (x, y) will be (21, 36)
Therefore, the value of y-coordinate from the given information is 36.

Find the range of possible values for k.
Answers
The possible values of k such that the quadratic equation has real distinct roots are 1 / 2 and 2.
What are the possible values of k associated to quadratic equation?
In this problem we find the case of a quadratic equation, of which the values of a variable k must be found such that the polynomial have real distinct roots. This can be done by using the discriminant of the quadratic formula, which is defined below:
For a · x² + b · x + c = 0, the discriminant is:
b² - 4 · a · c > 0
Then, if we know that a = k - 1, b = 2 and c = 2 · k - 3, then the possible values of k are:
2² - 4 · (k - 1) · (2 · k - 3) > 0
4 - (4 · k - 4) · (2 · k - 3) > 0
4 - (8 · k² - 8 · k - 12 · k + 12) > 0
8 · k² - 20 · k + 8 > 0
Whose form form is shown below:
8 · (k² - (20 / 8) · k + 1) = 0
8 · (k² - (5 / 2) · k + 1) = 0

Students make 97.5 ounces of liquid soap for a craft fair. They put the soap in 6.5-ounce bottles and sell each bottle for $5.50$. How much do the students earn if they sell all the bottles of liquid soap? Explain.
Answers
The students will earn $82.5 if they sell all the bottles of liquid soap.
What is a unitary method?The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Given that,
Total amount of liquid soap prepared by the students for a craft fair =
97.5 ounces
Weight of each bottle in which students poured the soap = 6.5 ounces
Let us first calculate the number of bottles, each contains 6.5 ounces of soap from 97.5 ounces of soap.
So, Number of bottles = [tex]\frac{97.5}{6.5}[/tex] = 15
It means, 15 bottles are prepared which contains 6.5 ounces of soap from 97.5 ounces of soap.
The amount at which each bottle is sold = $5.50
The total amount earned by selling all the bottles of liquid soap = 15×$5.50 = $82.5
Hence, The students will earn $82.5 if they sell all the bottles of liquid soap.

scores on an iq test are normally distributed. the test is designed so that the mean is 100 and standard deviation is 15. (a) what percentage of the population has an iq above 120?
Answers
From the normal distribution it is calculated that 9.18% of people has an iq over 120.
Normal distributions are crucial to statistics because they are widely used in the natural and social sciences to represent real-valued regressors with unknown distributions.
Some of their significance can be attributed to the central limit theory. This claim states that, in some cases, the average of many samples (observations) of a stochastic process with limited mean and variance constitutes itself as a random variable, whose distribution merges to a normal distribution as the number of samples increases.Because of this, the distributions of physical values, such as error margins, which are expected to be the sum of many independent events, are frequently near to normal.We have to find P( X > 120 )
Thus find z score for x =120
[tex]z=\frac{x-\mu}{\sigma}=\frac{120-100}{15}=\frac{20}{15}=1.33[/tex]
Thus we get:
P(X>120) = P(Z>1.33)
P(X>120) = 1 - P(Z<1.33)
P( Z < 2.67) = 0.9082
Thus
P(X>140) = 1 - P(Z<2.67)
P(X>140) = 1 - 0.9082
P(X>140) = 0.0918
Percentage = 9.18%
Therefore 9.18% of people has an iq over 120.

A woman bought some large frames for $10 each and some small frames for $5 each at a closeout sale. If she bought 23 frames for $160, find how many of each type she bought
Answers
A woman purchased 12 little frames and 10 large frames.
We create an algebraic equation in this question.
Algebraic equation: what is it?An algebraic equation is a mathematical statement that makes two expressions equal to one another.
In most circumstances, an algebraic equation consists of a variable, coefficients, and constants.
According to question, the equation will be
Let x = large frame
y = small frame
x + y = 22 ---(1)
10x + 5y = 160 ---(2)
Now, solve the eq(1) and eq(2),
we get, x = 10
and, y = 12
If you want to cross-check you can do like that,
large frame price = $10
and, x = 10 (means 10 large frames women bought)
so the price will be = $ 10 * 10
= $100
Now, for the small frame price = $5
and, y = 12 (means 10 large frames women bought)
so the price will be = 12 * $5
= $60
Now total price is given = $160
and if we add both the prices of large and small frames = $100 + $60
we get, same as total price = $160
Therefore, we can say that woman bought 10 large frames and 12 small frames.

Answers
The translation from AB to A’B’ is (x, y) → (x + 9, y + 2).
What is Translation in Math?The translation is a type of transformation in mathematics. When a shape is transformed, the original shape is referred to as the preimage, and the translated shape is referred to as the image.In mathematics, a translation is the movement of a shape to the left or right and/or up or down. The translated shapes appear to have the same size as the original shape, and hence the shapes are congruent. They were simply relocated in one or more directions.Given:
The coordinates of A(preimage) are (-5,1).
The coordinates of A'(image) are (4,3).
From the coordinates of the translated image, A'B' we can determine the transformations.
The translation applied to the point (-5,1) are (x, y) → (x + 9, y + 2).

Answers
Step by step
Using y intercept form
y = mx + b
Flat fee of $115 is y intercept or “b”
The $12.50 per hour is the rate or “m”
$152.50 is the total
So your equation is
$152.50 = $12.50x + $115
To solve subtract $115 from both sides to isolate x
$152.50 - $115 = $12.50x + $115 -$115
$152.50 = $12.50x
Divide both sides by $12.50 to solve for x
x = 12.2 hours

The values of x = 14 and y = 12
In the diagram given, there are two parallel lines and three angles formed by cutting the parallel lines.
So here, angles (2x+7)° and (3x-7)° are corresponding angles.
That is they occupy relatively same position, that is both are above each parallel line.
So they are equal angles.
i.e., 2x+7 = 3x-7
⇒ 3x-2x = 7 +7
⇒ x = 14
Now the angles 2x+7° and 12y+1° are supplementary angles.
Supplementary angles are formed on a straight line between a line cutting the straight line.
That is their sum = 180°
i.e., 2x+7° + 12y+1° = 180
⇒ 2 x 14 + 7 + 12y +1 = 180
⇒ 28 + 8 +12y = 180
⇒ 36 +12y = 180
